In kvm_stat we grovel through /sys to find out how many cpus are in the system. However if a cpu is offline it will still be present in /sys, and the perf_event_open() will fail. Modify the logic to only return online cpus. We need to be careful on systems which don't support cpu hotplug, the online file will not be present at all.
